NOTE: General Precautions and Warnings
WARNING
To avoid risk of personal injury or death due to electrical shock, disconnect electrical power to unit
before attempting to service the unit.
WARNING
To avoid risk of personal injury or death due to electrical shock, DO NOT, under any circumstances,
alter the grounding plug .Air conditioner must be grounded at all times. Do not remove warning tag
from power cord. If a two-prong (non-grounding) wall receptacle is encountered, contact a qualified
electrician and have the receptacle replaced with a properly grounder wall receptacle in accordance
with the National Electrical Code.
WARNING
To avoid risk of heat exposure, which may cause death or severe illness, air conditioner must be
monitored when failures or shuts down.
WARNING
To avoid risk of personal injury or death due to electrical shock, grounding wires and wires colored like
grounding wires are NOT to be used as current carrying conductors. The standard accepted color
coding for ground wires is green or green with a yellow stripe. Electrical components such as the
compressor and fan motor are grounded through an individual wire attached to the electrical
